To all w/wm it may concern: i

.Be it known that I, Piume A. KOEHRno, a citizen of the yUnited States, residin at Milwaukee,county of Milwaukee, and tate of Wisconsin, have invented new and useful Improvements in Concrete-Distributors, of which the following is a specification.

The object of my invention is, more especially amongr other things, to provide a.

i 1. device to be used in 'laying walks and street pavements in, connection. with a concrete mixer for receivingthe mixed-cfmcrete as it is discharged from the mixing drum and conveying it to the place of deposit in the walk or pavement which is being laid, andi the same is explained by reference tothe accompanying drawings, in which,

Figure 1 represents a side view thereof in connection with the supporting frame of an ordinary concrete mixing machine. Fig. 2 is a detail showing an end view of the cable operating mechanism by which` the conveyer of concrete is operated. Fig. 3 is a diagrammatic view in perspective of the cable supporting rollers and pulleys which are employed in moving the conveyer. Fig. 4 is a detail plan of the turn table and operating mechanism. F ig. 5 is a topview andy Fig. 6 a vertical section ofthe concrete receptacle. Fig. 7 is a side view of the discharge controlling operating device.

Like parts are identified by the same ret erence numerals throughoutthe several views.

1 is an ordinary concrete mixing drum, and 2 represents a portion of the end frame from which the drum is supported-in connection with my concrete conveyer.

3 is a swinging crane, which is provided upon its sides with a track 4 upon which the carriage 5 is supported and operated.

6 is a receptacle into which the concrete is discharged from the drum l through the stationary trough 7. The receptacle 6 is connected with the carriage 5 through the vertical hangers 8, and the carria e 5 is provided with a plurality of ro lers 9 adapted to operate on the track 4 as the receptacle 6 is moved forwardly and backwardly along the crane 3 from the mixing drum to the place of deposit. The crane 3 is supported from the vertical frame 2 through the bracket 10, trunnion 11, turn table 12, vertical lugs 13 and pivotal bolt 14. The trunnion 11 is supported at its lower end from the bracket 10, While its upper end is centrally 'connected with the table perfo-rms a partial revolution as the' crane 3 isring to the right and left. The receptacle 6 which is adapted to he moved longitudinally on said track 4 may? he brought to any desired point of deposit within the radius described by said' swinging crane.

15 is a worm shaft which is revolsu'oly sup ported in suitable journal hearings au Seid bracket 10 and is adapted to engage in the teeth 16 formed in the edge of the turn table 12, whereby as the shaft .15 is turned for v wardly or baekwardly, the turn table 12 emi the crane 3 supported therefrom are caused to describe a partial revolution to. the right or left.

17 is an operating crank, which. is rigidly connected with the worm shaft 15 by which the same is manually operated. While the worm Shaft l5 may be manually operated with a crank, a belt or pulley, or equivalent mechanism may be substituted thereor.

19 is a cable by which the carriage 5 and receptacle 6 supported therefrom are drawn forwardly and backwardily upon the crane. 011e end of said cable 19 is connected with the carriage 5 at the point 20, and it extends from thence around the outer end of the crane and passes over and upon the pulley 21 from thence around the pulley 22, from thence over the drum 23 and from thence backwardly and forwardly between the drum 23 and drum 24 around which drums ,it passes a plurality of times whereby the reqiliiredfriction is produced between said cab es and the drum 24 to prevent it from slipping, when the cable asses from the pulley 23 partially aroun the pulley 25, from thence around the pulley 26 and from thence to the other side of the carriage 5 with which it is connected at the point 27. The pulleys 22, 25 and 26 have journal bearings in an integral part of the crane at its rear end. The drum 23 has journal bearing's in the hangers 44, which hangers are when by a reversedV movement of the drum suspendedv from the up er end of the frame Y 24, the cable 19 will be moved in. the opposite direction, whereby the receptacle 6 f the crane. 1

' porting shaft 34. Thogears 32 and 33 are Motion is 'communicated from the mixing drum 1 to the cable 19 either forwardly or backwardly through the gear wheel 28, pinion 29, shaft 30, pinion 31 and reversely revoluble gears 32 and 33 and the drum supadapted to revolve freely upon their supporting 4shaft 34, and motion is eommunicated from either one of said gears 39,-33 to the drum 24 yat the will of the operator through the clutch mechanisms 35 and 36. The clutch mechanisms 35 and 36 are respectively connected with fthe supporting shaft 34 and adapted to revolve therewith. When, however, the clutch mechanism is brou'ghtinto engagement ywith either one of said gears 32-33, motion is communicated` from said gears through said clutch mechanism to said shaft 34, and from said shaft to the drum 34', whereby said drum is revolved. When the clutch mechanism' 36 upon the right is clamped to the gear wheel 33,7the drum 34 is revolved in one direction. When, however, the clutch mechanism 35 upon the left is brought into engagement with the gear 32, the drum 34"is revolved in the opposite direction. lVhen, however, both clutches are thrown out of engagement with said gears, the drum is permitted to stand at rest. Thus it will be obvious, that while the driving shaft 30 and gears 32 andy 33 are continuously revolved in the same direction, the drum 34 and the cable operated thereby, may at the will of the operat'or, be moved in either direction or permitted to-stand at rest.

37 and 37 are slidable collars supported upon the shaft 34, and said collars are provided'with outwardly diverging bearings 38-38,which are adapted to contactwith the arms 3.,*,39 of the clutch mechanism as said collars are moved inwardly, whereby said clutch mechanism is operated and caused to impingc against thebearings of said gears32 and 33. The-collars 37 are respectively provided with radial flanges 3939"formed for the reception of the operating levers 40. The operating levers 40 are pivotall connected to the bracket 41 by the bo ts 42, while the free ends of the levers serve as handles for operating said clutchAmechanisms.

To produce the required tension and friction offthe"operating cable" 15)',1 Ithe iipper drum 23 is adjustably supported from the upper end of the frame 2l through the shaft 43.vcrtical hangers 44444, movable journal bearings and adjustable screws 46, which adjustable screws 46 have threaded bearings in the lower ends 47 of said hangers 44, whereby by turning said screws 44 upwardly and lawnwardly the tension of the cable 19 ma be increased or diminished at pleasure.

The outer end of the crane 3 issupported at any desired angle o'r elevation above its 'pivotal support 14 by the cable 43, one end of said cable being connected with the outer end ofthev crane through the bracket 49 and bolt I()s when it passes from thence over the pulley 51 and from thence over the pulley 52, and from thence to the drum 53.

'lh-e pulley 51 is connected with the top of I the frame 2 through the bracket 54, pivotal bolt link 60 and pivotal bolt 61, while the pulley 52 is connected with the outer end of the crane through said bracket 49 and bolt 50, the drum 53 being centrallyfsupported from and connected with" the crane 3 through the bracket 62 and drum'supporft l ing bolt 63. 64 lis a crank by which the drum 53 is revolved. 66 is a ratchet wheel connected at one en d to said drum, and 67 1s a pawly operating on said ratchet wheel and serves to hold the drum at any desired point of adjustment. The pawl167 is pivotally supported at its lower end from the crane 3 upon the bolt 68, and its fupper end 1s adapted to engage the teeth of said ratchet. Thus it will be understood that when desirous to raise the outer end of the crane, the crank 64 is revolved from left to` right, whereby the cable 48 will "be wound upon the drum 53 luntil thelcraine is brought to the desired point of adjustment, when it will be retained atsuch point bythe drum retaining pawl 67. By thev reversed Inovement of the crank 64, the cable 48 is slackened and the crane 3 is lowered.

For convenience in discharging the contents of the receptacle G, the bottom of said receptacle 6 -is formed in two parts 68-68, which are pivotally connected with the sides of the receptacle by the boltsV 6.9-69, and the opposing edges of said bottom members are `supported in their closed position from the carriage 5 through the rods 70, bolt 71,

When the crank' 6 is permitted vt/o tiow thererom'glthe place of deposit.

Having thus described, my invention what T claim as new and desire to secure by Tmters Paten-t, is: f

.1. In a' device of the described class, the combination of a vertical frame, manually actuated means for revolving said frame a partial revolution around its pivotal support, a crane pivotally supported at one end from said frame, a track carried by said' crane, a cari-ia e mounted upon said track, a cable suspen ed from said carriage, a receptacle suspended from said cable, means for communicating a forward and backward movement to said carriage, and means carried by said crane for raising and lowering the same.

2. In a device of the described claws, the

combination of a vertical frame, a plurality of pulleys connected with the respective ends of said frame, means for raising and lowering the pulle s, supported from the upper end of said ame, and thereby regulating the tension of a cable, manually actuated means for revolving said frame a partial revolution around its pivotal support, a crane pivotall supported at one end from said vertical rame, a track carried by said crane, a carria e mounted on said track, a cable suspen ed from said carriage, a receptacle, suspended from said cable, a drum mounted on said crane, a pulley connected with the upper end of said vertical frame, a cable Communicating between said drum and pulley, and a crank for revolvin said drum, whereby as Said drum is revo ved in opposite directions, said 1 crane is adapted to be raised and lowered, Lall substantially as and for the purpose specified.

In testimony whereof I ax my signature in the presence of two witnesses.
